Question
What is that difference between the security six and the GP100?
The GP 100 is a beast
The SP101 is a small like a K-frame
Where does the security six fit in there

I've had a couple 4" GP100s along the way. For some stupid reason, I let them go. I do have a late model Security Six, it's a 4" HB (Heavy Barrel) model. The big differences I see is the GP100 has a different style grip frame, a heavier full length underlug, and an extra latch that secures the cylinder closed.
Other than that, the Security Six and the GP100 are very similar in overall size. The earlier Sec-Six had a slimmer barrel, and a slightly different grip frame shape.
